External Antenna for LTE?

Looking to get better LTE signal in my house where I get 0-2 bars, signal is there but sketchy at times.
Has anyone tried the external antenna port on the bottom back of the phone? Will this adapter work?

Then add this antenna:

Wilson electronics AWS LTE booster isn't offered till mid June according to their sales department. Looking for something to get me by till then.

What is your signal strength in dBm?
With those antennas, I believe they should work with the TB, but how well they will actually work is another question.

Where do I find dBm or what app?

that isnt too bad dude. not bad enough that i would buy an antenna. but you if you want to then i prob wont be able to convince you otherwise.
as far as will it fit? yes
will it work? yes
how well will it work? prob not as well as it should
as a side note Verizons 4G is not in the AWS spectrum but rather in the 700Mhz Block for LTE and VZE operates voice and 1X at 850 and evdo 3G at 1900 (pcs)

its not your phone, LTE is just not as good as it should inside homes, i really dont know why so I wont be able to answer that. My signal strength is -75 and I still get spotty coverage at home, sometimes it could go hours without dropping and sometimes it will drop like crazy. It is kinda crazy but it is what it is.
I can go outside and go to work 3 miles away and walk to the next block and as long as I am outside it works great. I think its just my house, or something lol. I dont know I have given up on it.
Oh by the way the bars dont represent the signal strength of 4g, the techs told me that it is only the voice signal strength and the bars have nothing to do with 3g or 4g signal. That was confirmed from 3 different techs.

Well I guess I can relate it to knowing what it could be and not getting it all the time. A lot of the time its 1-3 mbps and then if I hold the phone upside down, touch the tv antenna and do a flip right before I hit the speed test button I get 7-13 mbps. Seriously though I noticed it does better in certain parts of the house which is why I thought a antenna might help?

Yea my bad, Wilson electronics will release the AWS (T-Mobile 4G) first then the LTE will follow shortly after that AWS release.

Good to know. If I go a quater mile outside my house I can get full signal with 40mbps download speeds. I have been in other peoples houses and had a fast connection so I think it does have to do with where they are located. Anywhere in Plano its in the 20-40 mbps range. My friend said in Houston he received 55 mbps download speeds. Must be something with upgrading the towers and this new equipment, I just hope they get it figured out.
BTW- I have Clear Wimax and it is somewhat reliable but with full signal the latency and download speeds are lacking compared to LTE. I made a video showing this- http://www.youtube.com/watch?v=NCAdDurQDVQ

Ok,
So I have an adapter and an antenna, but my Samsung Charge has 4 ports. One L1R2, one L2, one R1, and an odd smaller sized one G.
Im assuming that the 3 normal ports are for its MIMO ability, but Im getting reduced signal not increased signal in each port.
Any thoughts?

I dont know if you purchased it or not yet but Verizon sells a device that increases the signal throughout your house without having to plug it into your phone. If you need a link just say but I would much rather that from the company I bought the phone than some off brand thing that may or may not work.
Plus the Verizon would would work with all Verizon phones in your house.

and my phones have almost never shown 3G, including the TBolt.
Since 4G came on last Friday testing in Indy, I have seen consistent 4G signal. That is consistent with the lower frequency being better at penetrations. In fact, it prompted me to put the Internet Connection widget on my desktop so I could turn off data instead of watching a huge battery drain.
That said, at home in a 4G fringe area, the only way to get 4G in my house is to walk to the window facing the direction of the tower. And the signal strength holding to the glass is about 10dB higher than just a few feet back.

Yeah,
Im not looking so much to improve call quality as I am looking to get 4G on a fringe area. Overcast days we get 4G from the reflection of the clouds, so I figured if I put a yagi on it I should be able to get 4G on a normal day.
I tried the normal connector that VZW normally sells for aircards. It cause a loss of signal in every port. But I looked at my neighbors Thunderbolt and saw that it had the same little port that my phone has that is marked G.
I ordered a plug for it and we will see if I get any boost from there.

So any good advise on making an external antenna for the thunderbolt? Has it been confirmed that the rubber round hole under the kick stand is indeed an external use for LTE antenna?
I talked with 3gstore and they recommended the use of the Wilson Electronics 801865 4G Verizon LTE Cell Phone Booster 70dB Adjustable Gain In-Building Wireless 700 MHz LTE Smart Technology Signal Booster but then again, that cost $350+.... can a simple hookup connector be connected to the phone with an outside antenna?
Thanks for your time,
David

By any chance you got a friend with an LG Revolution?
That phone will tell you for your dbm for 1X,3G, AND 4G.

I drove a truck for 5 years. Wilson has been selling this crap in every truck stop in America for at least as long and I've seen a lot of people buy it. The stuff I've used (other people's stuff) really hasn't done anything that I can tell. To me, it seems like a massive marketing gimmick. The stuff that actually connects to a connector on the device might show promise, but I'm not a fan of some 6 foot coax cable hanging off of a delicate connector soldered right to my board. I'm not really sure how effective any LTE solution would be either, since the LTE specification calls for dual antennas.
Bottom line: I've pretty much everything I've ever seen come from Wilson Communications is over-priced gimmicks that lack any sort of verifiable functionality.

I agree with the other driver. Most of the antenna stuff sold is a gimmick. I have a Verizon extender in my house. It only works on call quality. I only have. 1 EV signal at home with the extender. And it does not improve that. so I know that won't help the 4G signal get any better. But the extender does at times interfere with other cell phone calls of my neighbors within range of it.

OK so i have heard what not to get but haven't heard what to get in order to increase my bars on the phone within the house.

[Q] Cell reception and WiFi issues

I hope by posting this here we can find an answer to a problem that a lot of OPO users are complaining of. the device has a terrible cell and WiFI reception when compared to other devices in the same area and using the same wifi networks.
Cell reception:
I`m on a 4G network . however i find that i have 0-1 bar almost all of the time in areas where i used to have 3-4 bars. and as a result i constantly get missed calls notifications. I read that switching to 3G in the phone settings might help, and that`s when i ran into the second problem. Switching to 3G will indeed give me better reception 3-4 bars but then the whole connection becomes erratic, and the phone will go from 3 bars to ``no connection`` back to 4 bars 4 to 5 times every minutes and i will lose mobile data totally on 3G.
WiFi reception and connection:
I have a secure 802.1x connection at work spread over 2 buildings. the phone will connect to 1 only and will not connect to the same network in the other building at all. both have the same SSID , settings, and login information. but the phone will just cycle between `connecting`` to `` secured with 802.1x``. I tried all roms available and the only ROM that worked was `Gummy ROM``. only when using that ROM, is the phone able to connect to that WiFi network!! and i have no explanation for that.
All these problems I mentioned above are consistent across all roms and there seems to be no answer from OPO support or on the official forum for the phone. I hope someone can provide me with a solution or an answer to this.
Thank you all

I'm getting the same problems.
Where signal is always strong, it seems to work OK, but with weaker signal it just screws up!
Its really pissing me off as i've take the phone to work for the first time, just to find out I cannot get any signal there, where by my HTC Desire worked just fine.

Also getting exactly the same problems. It is impossible to use OPO where signal is not so strong although other phones work flawlessly. Reception signal strength goes up and down all the time from full to none bars. Data connection is inconsistent.
Anyone with weak inconsistent signal strength vote here: https://jira.cyanogenmod.org/browse/BACON-132

I still hope that what we are experiencing is due to firmware and drivers issues that can be solved by the developers on XDA. However, the complete silence by OnePlus and Cyanogen regarding this issue despite the number of people complaining, makes me worried that it's a bigger hardware issue that they are trying to avoid and move into "we'll fix it in the next version of the phone” kind of scenario.

That would be bad scenario. I hope that it is just software problems. But seeing how OnePlus deals with the problems I also have doubts.

I would say it's software baseband/modem and CM needs to step it up. My Nexus 5 has a better signal strength. But then Google has a much bigger development team than CM or One plus. My friend has the GS5 and it has the snapdragon 801 chip set and it has a much better signal strength.
So ether the One's antenna is not that great or it a software problem.
As you can see the controller is on chip.

I don't have it as bad as some have posted so hope things get fixed for all.

Yeah. Many users are having problems with cell reception.
It's a shame.

My wife & I both using OPO international version, both of us facing poor signal & sound problem when we get them. Sound problem is currently handled by boosting the sound but frankly the sound is a bit deteriorated. The signal problem is better a bit now by installing oppo 7 radio. Hope the team can put more effort on the signal problem. It is phone!

I have this issue too, but I think this is a hardware problem, because CM and OPO teams do nothing for fix this problem, and Chao Chen at CM Jira says that this poor signal is a normal... I realy think about selling my OPO and buy another phone...

I have pretty crappy signal on mine too (London UK). Signal strength fluctuates wildly even by moving the phone in a different direction. I've reverted to the previous modem via a flash .zip and things seem a bit better but it's early days. I would have thought that number 1 priority for a phone is that it actually works well as...well, a phone!
Disappointed that the 'giant killer' tag doesn't quite match the reality.
I sincerely hope there are improvements but I have my doubts.

I don't have this problem on O2 uk wonder if its anything to do with 4g which isn't supported on this network. Have any of you tried PAC rom.

This problem is really starting to be a major issue for me. I expected some improvement by now.
Does anyone know is this has been confirmed as a radio/kernel issue or a hardware issue (antennas maybe).

Wifi problems

has anybody else had WiFi problems with their 7pro? I had WiFi problems with my 6t as well it'll say connected no internet and the Wi-Fi is very slow opposed to data when there is no other problem with other devices using the same Wi-Fi connection. sometimes the Wi-Fi won't work at all even if my phone says it's connected apps will not load. I am on a t-mobile variant flashed to international since the day I bought it a week ago any insight to this would be great because I see that people have this issue a lotk

Yeah WiFi "speeds" on the 7Pro are abysmal. I have around 1/3rd to 1/4th the speed compared to my previous 5T. Something completely unexpected, thought the phone would be as least as fast if not faster.
Same thing on 9.5.5/9.5.7 and with various kernels

Yeah I'll vouch for that too. My WiFi speeds and connection strength for that matter are terrible! I came from a 6T that honestly had no problem with WiFi whatsoever, so this is annoying. Well, I hope the next update addresses WiFi, because the 7 Pro is a nice phone! It's a shame!

Add me as another for this list. My speeds are absolute crap, seemingly capped at 15mbps across all networks I've tried. My sons Pixel 3 on the other hand flies on the same. So not a router or ISP issue. So disappointed as everything about the 7 Pro is awesome but can't live with such poor WiFi, have a feeling it affects the HotSpot capability and speed too whatever the issue is.

Hi all!
I had that too - a simple wipe cache of all the phone's resources fixes the problem (turn off the phone then hold volume down and power button till the recovery mode kicks in and then just go to wipe cache and reboot, e voila!). I had some 10 MBps (lol!), now it is almost 80 Mbps, which is what I should get given my old WiFi system. Never settle!

Along with wiping the cache as the previous poster said...another thing that sometimes works is to reboot your router while at the same time doing a network reset on the phone. This way all the connections are fresh and new. I know this has been a solution for many different phones over the years. YMMV

T-mobile variant flashed to International
Same problem here. I have the T-Mobile variant and flashed international prior to 40 day unlock. It shows I have WiFi and or data but nothing loads. I rest my phone and all is good. It happens 2-3 times a day. I've tried wiping cache and it still happens. I vaguely remember having network issues before I flashed the international software but, I'm not sure if it's the T-mobile variant phone or if its international software. Any ideas?

Today my 5Ghz has just stopped working period. can't connect to a 5Ghz or use the mobile hot spot at 5Ghz which i did use every single day for work, now i have to use the 2.4Ghz but it is WAY slower. anyone figure out why?

Are you sure it's the phone?

seeing as i have now tried multiple locations and wifi's yes. and my work phone can connect just fine to all the ones including my home, just the oneplus can not.
it stopped while in use like it just died.

Does anyone know how to solve this issue yet? Can't seem to find any fix

I wonder why I got this slow, I used to have 100+ on my old iPhone X (same 5g wifi)

My wife and I both have this problem as well. Fortunately we have truly unlimited data, or tie would be unacceptable. Sometimes it's super fast, sometimes it's so slow apps decide you're offline. I've never seen any sort of fix; it's probably an OS/kernel level issue.

Same issue!!!
I have also created thread on onePlus official forum!

In Houston, I have no wifi issues with my 7pro on ATT!!!!

Router settings are going to play into this. Many variables beyond "my phone doesn't work" I can get over 200mbps on a fast router and connection properly configured for N or AC. Even on 2.4ghz, 60-100mbps works.

I just got this phone coming from a Poco F1 that decided to stop charging unless turned off and I've gotta say that this is very disappointing. First problem was that the phone wouldn't go above 10 Mbps. Changed my AC router config from 80 Mhz to 40 Mhz and that helped increase it to > 100 Mbps but if I go into Wifi settings the max the phone ever sees as receive/transmit speeds is 192 Mbps. It doesn't matter if it's 5 Ghz or 2.4 Ghz. Tried changing settings in the router and even tried a different router, same thing. Reset network settings, same thing. Reset the entire phone, same thing. This is the t-mobile unlocked variant of the phone.
Is there anything that can be done? Would a custom rom or converting it to the international version help?
EDIT: lol this is clearly either a hardware issue or some OS limit. I enabled hotspot and connected my Poco to it and the Poco also sees 192 Mbps max. This sucks...

I have the same problem with my op7P.
after downloading and installed an update, my WiFi could not be detected anymore....
it just could not find any WiFi
Needless to say, hotspot also failed.

I was able to fix my above problem (stuck at 192 Mbps max) by switching to the Pixel Experience ROM. Unfortunately, battery drain was excessive (and fingerprint stopped working out of the blue) so rolled back with MSM tool and upgraded to 10.3.3 using local upgrade. Back to stuck at 192 Mbps so this is definitely a rom problem.

I never had wifi problems with mine OP7 pro. Maybe a router problem!
I'm using 5Ghz and wifi rocks on Op7p.

VoLTE on Android 11

Hi
Got this phone a couple of days ago and in my excitement did all the updates including A11.
I'm getting no VoLTE option, my network, O2 UK supports it and my last few phones have had it.
Yesterday I factory reset, unlocked bootloader and rooted and for the life of me I still can't get it or WiFi calling to show up anywhere.
Has anyone got any tips or done the A11 update and VoLTE still works?
Thanks!

Thanks. Just for my own sanity I swapped out the sim into a Poco F1 running Pixel Experience and the option for 4g calling was there...so my sim/plan supports it. I'm just not sure how to get this phone to recognise it.
When I was out of the house this morning I got 4g+ so I guess aggregation is working, I don't live in a 5g area so don't have a 5g plan yet.
I'm rooted but I wouldn't know where to start, any tips or guides?
Edit - I've now tried both available UK Android 11 roms, O2 and customised, and neither work. I've also flashed, unrooted and relocked the bootloader and used the Xperia Companion to software repair.
So far, no luck. It's a shame as I absolutely love the phone, it's perfect for me and I'll put up with it but as it was an Amazon open box unit I'm wondering whether the previous owner has been "under the bonnet" before me and borked something.

I'm having the same issue, any idea how I can fix this?

Not sure to be honest.
In my case I sent back the open box unit I had and ordered an as72/256gb one from Wondamobile.
That was the same, no 4g/Wi-Fi calling, after a couple of days I contacted o2 who said it should be working but they re-enabled it and told me to restart the phone after 24 hours.
Still didn't work.
Then a couple of days later I noticed the option was enabled, so I don't know if it takes a few days to register on the network or something else.

I am also running as72 variant but in Canada and the cell reception is very bad for some reason. It jumps about from 0 bars to full bars and everything in between within 5 minutes even if the phone is just on a table. I also can't get volte either so I'm wondering if I need to do some firmware hacking to fix it? I called my cell company and they were typical zero help. At a loss now what to do...

And is it really that bad? Did you check SNR and signal strength in dBm and compared it to your old phone? (I recommend NetMonser app for this).
Because reality isn't that bad and whole problem is that bar indicator being too "honest". From my observation jumping bars occurs when telephone goes from 2CC or 3CC to 1CC / 2CC, because it shows strength of weakest carrier. This is more significant when you are on edge of coverage of that capacity carrier. This is big difference compared to all those Chinese phones, which always shows strength of strongest carrier (so jumping won't occur there).
At my home I am something like 100 meters from nearest cell tower. It provides coverage on two LTE bands: 20 (800MHz) which is supposed to have country coverage and 1 (2100MHz) which is used as capacity layer in more populated area. When I am outside there is no problem - 2CC and full bars. Inside house its different story. Upstairs I get something like 1 bar, because that 2100MHz signal is really weak due thick walls (As expected - don't forget that Wifi is on 2400MHz and it don't like walls either). Downstairs I actually get full bars - because guess what? Phone gets there only 1CC signal on 800MHz and that 2100MHz capacity is out of reach. Old phone just shows full bars everywhere, because it don't mind - 800MHz is strong everywhere at my house. And yet - it don't have 2100MHz reception downstairs either.
When I compared it to older phone I've got comparable signal levels (in dBm). Also I didn't find any new holes in signal coverage outside our town (I live in hilly area and on some places there is literally no coverage).
----------------
To that your VoLTE problem, that's different story - Your phone doesn't have modem configuration for your operator. Each phone variant have different set of modem configurations of supported operators (its market related)- if its not listed, provisioning won't start and because that treacherous VoLTE doesn't work if it is supported and enabled on phone and on operator network for your device and sim. Basically you are out of luck there. Only way to enable it is root your phone and add missing modem config for your operator from US variant (and even than it can fail, if your operator is picky - it most likely not worth the effort). Or may be by flashing XQ-AS62 firmware over XQ-AS72, but it also seems risky to me.

Thanks for the information. I now understand there's a lot more to it than just more bars = always more better. I will do some testing with netmonster app and report back.
------------------------
For volte it is not a big deal and I agree it may be better just to forget about it. I might try flashing USA firmware one day or root but for now I don't need volte.

I have done tests with netmonster comparing my sony and my galaxy S7 which always showed full bars. Same sim used, same placement (my basement), 3 minutes looking at the graphs and deciding rough average.
SAMSUNG showing full bars
Network: BELL 4G LTE 2600
SNR: 15
RSRP: -100
RSRQ: -6
RSSI: Not showing up
SONY showing 3 bars
Network: BELL 4G LTE 2600
SNR: 15
RSRP: -100
RSRQ: -8
RSSI: -70
SONY showing 2-3 bars
Network: BELL 4G LTE 1900
SNR: 6
RSRP: -95
RSRQ: -10
RSSI: -60
(Could not get my S7 to band 1900)
I dont really know what the numbers mean so please correct me but this seems to show that the phone receives signal on par with other phones but displays a more honest bar reading.

Note 10 Plus cellular reception

Just moved on from the S9 {SM-G960U1) to the Note10 Plus (SM-N975U1) and I'm experiencing some trouble: poor cellular reception.
This is not a lack of signal bars - I know those don't tell the story - this is a COMPLETE lack of service in areas where I usually have service. Today. I brought my second line - a Samsung S8 SM-G950U1 - with me and in about 75% of the areas I travel in, there was a complete lack of cellular signal while using the Note10 Plus meanwhile the S8 was pulling down 50 or 60 Mbps. Where there was a signal on the Note10 Plus, it would pull about 3 or 4 Mbps while the S8 was sitting at 80 or 90 Mbps.
What's going on? I already reset my Network Settings and the next day had my SIM card replaced. This was based on noticing that at my house where 80+ Mbps was routine with the S8 and the replaced S9 (SM-G960U1) the Note10 Plus can hardly muster 12 Mbps, usually 2 to 3 Mbps.
AT&T, just upgraded to their top plan with unlimited everything with no data throttling and 50GB hotspot per line. On Android 12 with the most recent updates. Sitting here with ZERO bars, no signal, thankful that there is Wi-Fi available.

Try in safe mode to rule out 3rd party apps.
Clear SIM toolkit data.
Network reset and clear system cache.
Ask AT&T advanced tech support to reset the network on their side.

Cleared data, reset network settings, and started in safe mode. ZERO signal. I'll call AT&T again. I called them Monday evening and they reapportioned the card and reset the signal then yesterday i had the SIM card replaced. I'll request advanced support.

When I was first messing with the phone earlier this week, I came across a menu that had about a dozen radio buttons to select I think it was network type. I remember it had some options but the top one was Automatic and I think CLTE/????? or something was selected. I got out of there quickly but now I want to look at it to see what the options were.

Here's mine:

I see one difference.
mnc number
If you replace the sim card, do it yourself and handle it like a stick of ram. It can be damaged by ESD, at least discharge yourself to a nearby earth ground before handling. They're a dime a dozen but a failure can be inconvenient and cause a lot of trouble.

I looked into the MNC. 280 and 410 are acceptable for AT&T and it depends on the SIM card number as to which one to use. 280 is correct for mine. Can't edit it anyway. It's locked to the SIM.

This is back home:
I mean, it's better than earlier in the week but I don't sit at home all day. To be sure, I'm perfectly happy with the above numbers. Hell, I'd even be happy if they were halved while out and about.

Those aren't good either... mind you there's a cell tower half a mile from me.
Maybe take it to a Samsung Experience center at Best Buy and let them run some advanced tests on it. See if they can pinpoint it.
Or return it.

I might be prolonging the inevitable but I messed around with it some more. Can you tell me what the preferred network is shown when you look in the phone info at *#*#4636#*#*

This thing is just junk. I got T-Mobile prepaid just to see if there's a difference and there is. It's slightly better. The same dead spots are there but they're briefer and the service is sometimes faster. Side by side another phone in the T-Mobile store where you know they boost that signal and I could barely manage a third of the other phone. Now, T-Mobile limits the prepaid customer to 65% of rated but it wasn't even close. We made sure we were using the same Speedtest server and he turned off 5G data. I'm going to perform a factory reset and try agdin but that's not going to work. If it doesn't work as a phone, what good is it?

No issues on either one of my Snaps N975U/1.
Both run well on AT&T. Same sim card for over 2.5 yo.

The phone is not junk. It's a good device. It's just not working here.

Not sure what the problem is especially if you have a good signal. My guess is that device itself. I spend little more time then it took to put in the sim card to set up the connection on the newest one.

I factory reset this morning with the AT&T SIM installed. I don't want to speak too soon but at my house, the speed test results are more than 60 Mbps every time. The last five have been over 100. Still have to take it out on my travels and see if there's an actual, real difference but that seems better.

Remember to turn on/off airplane mode when traveling if it has trouble in an area to reset the tower it's using.
Try a hard reboot:
Press and hold the Volume Down button first and don’t release it.
While holding it down, press and hold the Power key.
Keep both keys held down for 10 seconds or more.

I took my S8 and the Note out Thursday morning and compared them. Both are my phones and on the same AT&T plan. The Note just has a very difficult time picking out a good signal. I spent about 5GB of mobile data running speed tests, drove over 100 miles, and walked almost four miles. Where the S8 would aggressively cycle through the bands to maintain some connectivity - be sure, there were plenty of slowdowns - the Note just camped out. RSRP numbers ran -10 or more even up to -20 lower on the Note than the S8 across the board. What I learned is that the signal is not that effective in a lot of areas around my parts but I'm not asking for that or super-fast speeds. I just need to look stuff up from time to time and stream music. Most importantly, i need to be able to use my phone as a phone. It can't even do that well. Maybe it's defective but I'm not willing to go through this again. Looking at the Xperia. Had Sony phones in the distant past and looked at them before I got the S9 a few years ago. Just started looking, not really sure what I'll do.

Something about that copy. I'm not seeing that issue with either one of the two I own. My download speed was substantially higher.
